RADIATOR.

To all whom it may concern:

Be it known that I, DAVID O. PARKIN, a citizen of the United States, residing at Venice, in the county of Los Angeles and State of California, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to a radiator of the type employed in conjunction with internal combustion engines.

An object of this invention is to provide a construction in radiators of the above character whereby radiators of various water capacity relative to a fixed size and number of units may be formed from a uniform blank, and another object is to provide a blank for forming the side walls of a water passage such that by varying the position of adjacent blanks transversely relative to each other the cross sectional area of the space therebetween may be increased or diminished to provide greater or less water space as occasion may require so that a radiator may be formed from a blank of fixed proportions to suit various requirements.

Another object is. to provide a radiator of the class specified embodying a series of rows of straight vertical water passages or conduits which are formed by joining a pair of corresponding sheet metal strips having longitudinal channels or corrugations thus providing a simple construction and also producing a radiator which can be manufactured at comparatively small cost.

A further object is to provide a radiator having an effective cooling surface so formed and arranged as to deflect air currents passing between adjacent water passages in such manner as toinsure thorough absorption of heat radiating through the water passage walls.-

Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a detail in horizontal section showing the manner of forming and arranging a pair of corrugated strips to form adjustable water passages.

Figure 2 is a detail in perspectlve of a fragmentary portion of a radiator as formed of the blanks shown in Figure 1.

Figure 3 is a detail in vertical section illustrating the manner of mounting and arranging the spaced fin to form air passagesbetween the vertical water conduits.

Application filed April 28, 1920. Serial No. 877,323.

Figures 4, 5, and 6 are details in perspect1ve 1llustrating modified forms of the invention.

In carrying out my invention, I employ a strip of thin sheet metal which is corrugatedto form a blank 7 with a series of longitudmal corrugations so that when a pair of the corresponding strips are placed face to face with the opposed corrugations nestmg out of alinement or register with each other vertical passages or conduits 8 will be formed between the adjacent strips,

In the preferred embodiment of my invention, as shown in Figures 1 to 3 inclusive,

the corrugationsvare substantially V-shaped in cross section and are formed with side Walls 9 and 10 of different lengths extending at an obtuse angle relative to each other and terminating in the apices of thefcontlguous reverse corrugations on correspondmg planes, so that the ridges of the corrugations on both sides of the strip will be alined throughout the width thereof.

In assembling a pair of strips to form the Water spaces 8, the corrugated strips are placed face to face with the corresponding corrugations nesting together, that is, with the adjacent elongated walls 10 abutting against each other and so arranged that the short walls 9 will be spaced apart to form the vertical conduit or water passages 8 therebetween. This arrangement of the strips permits forming of the water space with various cross sectional areas, as indicated for example in dotted lines in Figure vide a column of greater or less volume, ac-

cording to the requirements of a particular form and size of blank being adapted to form radiators having various sized water spaces as occasion may require. For example, where the engine is of such character that quick cooling of the water content of the radiator is necessary, the blanks will be arranged to form narrow water spaces to contain a small body of water.

water which would be quickly cooled, and on the other hand where itis desirable to employ a large volume of water, the blanks would be assembled to space the walls 9 further apart and thus increase the water space so as to accommodate a large volume of In this manner various requirements may be met and radiators constructed to adapt them to varying conditions by the use of a single size of blank, thus obviating the necessity of forming various sized blanks in constructing radiators of various capacities.

In constructing the radiator the blanks are connected together by soldering the edges thereof, as is common in radiator construction, and the units formed by the connected pair of blanks are spaced apart by corrugated fins 11 of'any suitable construction.

' As a means for seating the fins between the adjacent units the ridges of the corrugations of the latter are formed with transverse indents 12 in which the ridges of the corrugations of the blank are adapted to seat. In some instances the indents may be formed in the ridges of the corrugations of the fin to form seats for the, vertical ridges of the blank. The upper ends of the assembled units are embedded in solder bodies 14 as is common in radiator construction.

In the modified form of the invention shown in Figure 4, the blanks are formed with lengthwise corrugations of such shape that when a pair of blanks are placed back to back a hexagonal water space 15 will be formed. In the form of the invention shown in Figure 5' the corrugations will be formed in a manner substantially corresponding to that shown in Figures 1 to 3 inclusive, but

the blanks will be positioned back to back so as to form diagonally extending water spaces 16 having a cross sectional area in the form of a parallelogram. In the form of the invention shown in Figure 6 the corrugations in'the blank are arcuate so that when a pair of blanks are placed back to back a water space 17 will be formed of substantially circular cross section. In the Figures 4, 5, and 6 the spacing fins 18, 19,

and 20 will be indented on their ridges to conform to the contour of the corrugated blanks.

While I have shown and described a specific embodiment of my invention, I donot limit myself to the exact details of construction shown, but may resort tosuch changes and modifications as occasion may require and as may come within the scope of the appended claims without departing from the spirit of my invention.

I claim:

1. In a radiator, a pair of complementary blanks having vertical V-shaped corrugations, said blanks arranged in nested engagement with each other with one wall only of each of the corrugations on one blank abutting against the corresponding corrugation on the other blank; the other opposed walls of the corrugations being spaced apart to form a vertical water space therebetween.

2. In a radiator, a pair of corresponding strips formed with corrugations extending lengthwise of the strips, said strips arranged face to face in corresponding positions with the inclined walls on one side of the corrugations of the adjacent strips abutting against each other andthe walls forming the other side of the corrugations spaced apart to form water spaces therebetween; said strips being adapted to be disposed in various positions relative to each other, yet maintained in contact, to vary the cross sectional area of the "water space.

3. A radiator comprising, a pair of complementary blanks having vertical V-shaped corrugations, said blanks arranged in nested engagement with each other with one wall of each of the corrugations onone blank abutting against the corresponding corrugation on the other blank; the other opposed walls of the corrugations being spaced apart to form a vertical water space therebetween. the apices of the corrugations being formed with indentations, and spacing fins seating in said indentations.
